Update.

I replaced the PRAM battery and I got the same symptoms.  As a next 
step, I pressed the SMU reset on the motherboard, and reset the PRAM 
(Alt-Option-P-R) at boot.  From that time on, things seem to work.  I 
successfully built my own kernel.  I left it overnight to build world. 
The ramdisk I created for /usr/obj was too small, so the build failed, 
but there were no hangs.  The machine was still up and running in the 
morning.

Thanks again!
